Making ductile cast iron with ESR process under D.C. condition without adding spheroidizing inoculant alloys has been studied in laboratory. The key operation of ESR for cast iron is increasing the silicon content in unrefined consumable electrodes of flake graphite cast iron and using CaF2-based slags containing rare-earth or basic oxides and magnesium fluoride. The samples excel ductile cast iron produced by general technological process in fatigue strength and sealing performance.
